Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and more specifically to integrated stoves and integrated stove cleaning methods. Background Technology

[0002] An integrated cooktop is a kitchen appliance that combines multiple functions such as a range hood, gas stove, disinfection cabinet, and storage cabinet. Because it includes a range hood, existing integrated cooktops have an oil cup to collect the grease drawn into the cooktop. This oil cup is usually removable, allowing users to clean it after regular use and preventing excess grease from overflowing into other parts of the cooktop and causing excessive pollution.

[0003] However, in actual use, users often do not empty the waste oil in the oil cup regularly and in a timely manner, causing the waste oil to overflow frequently, which in turn creates excessive cleaning pressure and seriously affects the user experience. Summary of the Invention

[0022] The liquid level control component is configured to be electrically connected to the control module and to control the connection between the oil storage chamber and the reaction chamber to be open or closed when the integrated stove turns on / off the oil drain mode.

[0023] As a further preferred embodiment, the liquid level control component includes:

[0024] A baffle plate is slidably disposed in the connection passage between the oil storage chamber and the reaction chamber, and can be slidably made to open or close the connection passage.

[0025] A drive device that is connected to and used to drive the baffle plate to slide;

[0026] The drive unit is configured to be electrically connected to the control module and to control the baffle plate to slide to a state where the connection passage is open or closed when the integrated stove turns on / off the oil drain mode.

Furthermore, by reacting the waste oil with the alkaline reaction reagent before discharge, the efficiency of waste oil discharge is improved.

[0047] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

[0054] Figure 6 The diagram shows the reaction between oil and an alkaline reagent. Detailed Implementation

[0055] The present invention will be specifically illustrated below with reference to embodiments:

[0056] Example 1:

[0057] Integrated cooktop, as attached Figure 1 As shown, it mainly includes a lower-level machine 1 and a higher-level machine 2 installed on the lower-level machine 1. The higher-level machine 2 has a cavity-shaped smoke inlet channel 2.1 for external oil fumes to enter; and the lower-level machine 1 has a cavity-shaped smoke collection chamber 1.1 connected to the smoke inlet channel 2.1 and for oil fumes to flow into from the smoke inlet channel 2.1.

[0058] Meanwhile, the smoke collection chamber 1.1 is equipped with a fan assembly 1.18 that sucks up the oil fumes so that external oil fumes can enter the smoke collection chamber 1.1 from the smoke inlet channel 2.1.

[0059] The fan assembly 1.18 mainly includes a fan housing 1.181 placed in the smoke collection chamber 1.1. The fan housing 1.181 has an internal mounting cavity, in which a fan 1.182 is installed to draw in oil fumes by rotation. Furthermore, the fan housing 1.181 is provided with a smoke inlet connecting the mounting cavity and the smoke collection chamber 1.1, and a smoke exhaust duct 1.183 connecting to the mounting cavity. The smoke outlet of the smoke exhaust duct 1.183 is used to connect to the building's smoke exhaust channel.

[0060] When the integrated stove is absorbing cooking fumes, the fan 1.182 is turned on and forms an airflow within the mounting cavity that discharges the fumes inside the fan housing 1.181 outwards through the exhaust duct 1.183. At this time, cooking fumes from outside the integrated stove enter the smoke collection chamber 1.1 through the smoke inlet 2.1, and then enter the mounting cavity of the fan housing 1.181 through the smoke inlet, and are discharged outwards through the exhaust duct 1.183.

[0061] During this process, some of the waste oil in the fumes will adhere to the inner wall of the fume collection chamber 1.1 and accumulate at the bottom of the fume collection chamber 1.1. Therefore, the lower-level machine 1 will also be equipped with an oil collection chamber located below the fume collection chamber 1.1. The bottom of the fume collection chamber 1.1 is provided with an oil collection channel 1.3 for the oil in the fume collection chamber 1.1 to flow into the oil collection chamber. After the above-mentioned fume extraction process, the waste oil remaining in the fume collection chamber 1.1 will flow into the oil collection chamber through the oil collection channel 1.3.

[0062] The cavity wall at the bottom of the smoke collection chamber 1.1 is preferably inclined, which can guide the waste oil in the smoke collection chamber 1.1 to the oil collection channel 1.3, so that more and better waste oil in the smoke collection chamber 1.1 can flow into the oil collection chamber for centralized treatment.

[0063] In existing methods, an oil cup with a drawer structure is often installed in the oil collection chamber. This allows the oil cup to be pulled out and cleaned periodically once it is full, thus enabling regular waste oil disposal. However, in actual use, users often fail to empty the oil cup regularly, leading to frequent overflows and excessive cleaning pressure, which severely impacts the user experience.

[0064] Based on this, this application mainly improves the waste oil treatment structure, specifically:

[0065] As attached Figure 2 To be continued Figure 3 As shown, this embodiment also includes a reagent chamber 1.5, which stores alkaline reaction reagents (such as sodium hydroxide and potassium hydroxide, which can undergo saponification reactions with waste oil). The reagent chamber 1.5 is connected to the oil collection chamber via a reagent flow channel 1.51. For example, the upper opening of the reagent flow channel 1.51 is connected to the bottom of the reagent chamber 1.5, and the lower opening is connected to the oil collection chamber. The upper opening of the reagent flow channel 1.51 is higher than the lower opening, so that the alkaline reaction reagent in the reagent chamber 1.5 can automatically flow into the oil collection chamber. Alternatively, an additional auxiliary device (such as a water pump) can be provided to allow the alkaline reaction reagent in the reagent chamber 1.5 to flow into the oil collection chamber.

[0066] Furthermore, the reagent flow channel 1.51 is equipped with a reagent control component 1.52 for controlling the flow of the reagent flow channel 1.51. When the alkaline reaction reagent in the reagent chamber 1.5 can automatically flow into the oil collecting chamber, the reagent control component 1.52 can be a solenoid valve for controlling the flow of the pipeline; when additional auxiliary equipment is required, the reagent control component 1.52 can be a water pump.

[0067] The oil collecting chamber is also connected to a drain pipe 1.6 for discharging fluid from the oil collecting chamber. The drain pipe 1.6 is equipped with a first water pump 1.7 for driving the fluid from the oil collecting chamber to be discharged.

[0068] The oil collecting chamber is also equipped with a level gauge 1.19 for monitoring the liquid level in the oil collecting chamber. The level gauge 1.19 is a commonly used device in kitchen equipment for monitoring the liquid level. Those skilled in the art can directly select it from the existing technology based on the description of this application to achieve the technical solution of this application, and it will not be described in detail here.

[0069] The integrated stove also includes a control module for electrical connection to a power source. The reagent control unit 1.52, the first water pump 1.7, and the level gauge 1.19 are all electrically connected to the control module. The control module supplies power to the reagent control unit 1.52, the first water pump 1.7, and the level gauge 1.19, and controls the opening and closing of the reagent control unit 1.52 and the first water pump 1.7. Furthermore, the control module is configured to: control the integrated stove to activate the oil draining mode when the liquid level in the oil collection chamber reaches a set height, and control the integrated stove to deactivate the oil draining mode after a set time.

[0070] To be precise, activating the oil-draining mode means:

[0071] The level gauge 1.19 continuously monitors the liquid level in the oil collecting chamber upon power-up and transmits the monitored liquid level value to the control module. The control module has a preset height value (set according to actual needs). The control module receives the liquid level value from the level gauge 1.19 and compares it with the preset height value. When the monitored liquid level value equals or exceeds the preset height value, the control module controls the reagent control component 1.52 to open for a period of time (the specific opening time is set based on the reaction ratio and the actual amount of waste oil collected in the oil collecting chamber when the waste oil reaches the preset height value; the amount of alkaline reaction reagent flowing into the oil collecting chamber is controlled by the opening time), allowing the alkaline reaction reagent in reagent chamber 1.5 to flow into the oil collecting chamber. After the opening time of reagent control component 1.52 is reached, the control module controls reagent control component 1.52 to close, thus sealing the reagent flow channel 1.51. At this point, the waste oil reacts with an alkaline reaction reagent (MOH, where the metal ion M can be sodium ion Na, potassium ion K, etc.) to generate a solution containing higher fatty acid salts (RCOOM is a higher fatty acid salt). The control module sets a reaction time, which is determined by the alkaline reaction reagent used and can be between 60 and 120 minutes (adjusted based on the reaction volume and temperature). During the reaction time, the control module keeps the first water pump 1.7 off. After the reaction time is reached, the control module turns on the first water pump 1.7 to drain the liquid from the oil collection chamber, thus initiating the oil drainage mode.

[0072] Turning off the oil drain mode means:

[0073] The control module is set with a start time for the first water pump 1.7. The start time of the first water pump 1.7 is set based on the amount of waste oil actually collected in the oil collection chamber when the waste oil reaches a set height value. After the start time is reached, the control module controls the first water pump 1.7 to turn off, thus completing one oil discharge action and turning off the oil discharge mode.

[0074] Furthermore, in order to improve reaction efficiency, the lower-level machine 1 may also be equipped with a heating element 1.10 for heating the oil collecting chamber. The heating element 1.10 is an electric heating element placed in the oil collecting chamber or placed outside the oil collecting chamber and attached to the side wall of the oil collecting chamber.

[0075] The heating element 1.10 is configured to be electrically connected to the control module and to be turned on / off when the integrated stove turns on / off the oil drain mode.

[0076] Specifically, the control module is electrically connected to the heating element 1.10 to supply power and controls the heating element 1.10 to turn on or off. When the integrated stove is in oil drainage mode, the control module controls the heating element 1.10 to turn on for heating. When the integrated stove is in oil drainage mode, the control module controls the heating element 1.10 to turn off. This thereby increases the rate of the saponification reaction.

[0077] To further improve reaction efficiency, a stirring device 1.9 can be installed in the oil collecting chamber to stir the contents of the chamber. (See attached image) Figure 3 As shown, the stirring device 1.9 includes a rotary motor 1.91 fixed to the top of the oil collecting chamber. The rotating shaft of the rotary motor 1.91 extends downward and is fixed to several (one or more) stirring rods 1.92.

[0078] The stirring device 1.9 is configured to be electrically connected to the control module and to be turned on / off when the integrated stove turns on / off the oil drain mode.

[0079] Specifically, the control module is electrically connected to the rotating motor 1.91 to supply power and control the motor to turn on or off. When the integrated stove is in oil drain mode, the control module controls the rotating motor 1.91 to turn on, driving the stirring rod 1.92 to rotate, thereby stirring and mixing the waste oil and alkaline reaction reagents mixed in the oil collection chamber, increasing the reaction speed. When the integrated stove is in oil drain mode, the control module controls the rotating motor 1.91 to turn off, thus increasing the saponification reaction rate.

[0080] After the stirring device 1.9 is installed, if the stirring device 1.9 and the waste oil are placed in the same space for a long time, the waste oil will stick excessively to the stirring device 1.9, causing the stirring device 1.9 to be unable to rotate smoothly and affecting the overall reaction rate.

[0081] Based on this, as attached Figure 3 As shown, the oil collection chamber in this embodiment includes an oil storage chamber 1.2 connected to the oil collection channel 1.3, and a reaction chamber 1.4 connected to the reagent flow channel 1.51. Waste oil in the smoke collection chamber 1.1 flows into the oil storage chamber 1.2, and alkaline reaction reagent in the reagent chamber 1.5 flows into the reaction chamber 1.4.

[0082] A level gauge 1.19 is installed in the oil storage chamber 1.2 to monitor the liquid level in the oil storage chamber 1.2; a stirring device 1.9 is installed in the reaction chamber 1.4 to stir the contents of the reaction chamber 1.4.

[0083] The oil storage chamber 1.2 is connected to the reaction chamber 1.4 (e.g., attached). Figure 3 As shown, the oil storage chamber 1.2 and the reaction chamber 1.4 are two parts of the same groove and are connected. The fluid in the oil storage chamber 1.2 can flow into the reaction chamber 1.4. The connection passage between the oil storage chamber 1.2 and the reaction chamber 1.4 is provided with a liquid level control component to control the opening / closing of the connection passage.

[0084] The liquid level control component is configured to be electrically connected to the control module and to control the connection between the oil storage chamber 1.2 and the reaction chamber 1.4 to be open or closed when the integrated stove turns on / off the oil drain mode.

[0085] That is, when the integrated stove is in oil drain mode, the control module controls the liquid level adjustment component to ensure that the connection between the oil storage chamber 1.2 and the reaction chamber 1.4 is unobstructed. The waste oil in the oil storage chamber 1.2 and the alkaline reaction reagent in the reagent chamber 1.5 both flow into the reaction chamber 1.4 to react in the reaction chamber 1.4 as described above and then drain the oil.

[0086] When the integrated stove closes the oil drain mode, the control module controls the liquid level adjustment component to close the connection between the oil storage chamber 1.2 and the reaction chamber 1.4. At this time, the waste oil in the smoke collection chamber 1.1 flows into the oil storage chamber 1.2 for storage and does not flow into the reaction chamber 1.4 equipped with the stirring device 1.9. This achieves the following: when draining oil as described above, the stirring device 1.9 can more smoothly assist the reaction to increase the reaction rate as needed.

[0087] The liquid level control component can be a valve structure that controls the opening / closing of the connection passage between the oil storage chamber 1.2 and the reaction chamber 1.4. Alternatively, for example, [the following is an example]. Figure 3 As shown, the liquid level control assembly includes: a baffle plate 1.81 slidably disposed in the connection passage between the oil storage chamber 1.2 and the reaction chamber 1.4, which allows the connection passage to be open / closed by sliding the baffle plate 1.81; and a drive device 1.82 connected to the baffle plate 1.81 and used to drive the baffle plate 1.81 to slide. The drive device 1.82 can be a push rod motor, whose telescopic push rod is connected to the baffle plate 1.81 to drive the baffle plate 1.81 to slide.

[0088] The drive unit 1.82 is configured to be electrically connected to the control module and to control the baffle plate 1.81 to slide to a state where the connection passage is open or closed when the integrated stove turns on / off the oil drain mode.

[0089] That is, the control module is electrically connected to the drive unit 1.82 and controls the drive unit 1.82 to turn on / off. (See attached diagram) Figure 3 As shown, when the integrated stove is in oil drain mode, the control module controls the telescopic push rod of the drive device 1.82 to move upward, thereby moving the baffle plate 1.81 upward and connecting the oil storage chamber 1.2 with the reaction chamber 1.4. When the integrated stove is in oil drain mode, the control module controls the telescopic push rod of the drive device 1.82 to move downward, thereby moving the baffle plate 1.81 downward and separating the oil storage chamber 1.2 from the reaction chamber 1.4.

[0090] Example 2:

[0091] Based on Example 1, this involves the reaction of waste oil with an alkaline reagent (MOH, where the metal ion M can be sodium, potassium, etc.) to generate a solution containing a higher fatty acid salt (RCOOM is a higher fatty acid salt). The hydrophilic portion of the higher fatty acid salt (RCOOM) consists of the carboxylate group and the metal ion. The carboxylate group has a negative charge and can form hydrogen bonds with water molecules, thus exhibiting hydrophilicity. The metal ion (such as sodium or potassium ions) also readily forms hydration with water molecules, thus also exhibiting hydrophilicity. These two portions together make the head of the higher fatty acid salt molecule hydrophilic, while the hydrocarbon group is hydrophobic. This structure allows the higher fatty acid salt to function at the water-oil interface, removing grease and grime through emulsification.

[0092] Therefore, directly discharging solutions containing higher fatty acid salts would result in a waste of resources.

[0093] Based on this, as attached Figure 4 As shown, the liquid outlet of the drain pipe 1.6 is placed in the smoke collection chamber 1.1 and is connected to a nozzle 1.11 for spraying out the liquid in the drain pipe 1.6. The spray nozzle of the nozzle 1.11 is set according to the structure to be cleaned.

[0094] Generally, the impeller of the fan 1.182 tends to accumulate a lot of oil, which affects its smoothness and speed of rotation, thus weakening the smoke extraction effect of the integrated stove. Therefore, as an implementation method, the spray nozzle of the spray head 1.11 can be positioned opposite the smoke inlet of the fan housing 1.181 and directed towards the impeller of the fan 1.182 inside the fan housing 1.181. In this way, when oil is drained as in Embodiment 1, a solution containing higher fatty acid salts, driven by the first water pump 1.7, can be sprayed onto the impeller of the fan 1.182 to clean the fan 1.182.

[0095] Whether it's cleaning the fan 1.182 or cleaning other components in the smoke collection chamber 1.1, a significant amount of liquid will accumulate at the bottom of the smoke collection chamber 1.1 after the spray cleaning is completed.

[0096] In one configuration, an additional drainage pipe can be installed to close the oil collection channel 1.3 during oil discharge mode and drain the liquid that has accumulated at the bottom of the smoke collection chamber 1.1 after cleaning. However, this would require at least two holes in the bottom plate of the smoke collection chamber 1.1, which would affect the structural strength. Furthermore, having two holes would impede the flow of waste oil.

[0097] Based on this, in this embodiment, as shown in the appendix Figure 5 As shown, a partition plate 1.12 is provided in the oil storage chamber 1.2, which divides the oil storage chamber 1.2 into a first oil chamber 1.21 and a second oil chamber 1.22 that are spaced apart vertically. The first oil chamber 1.21, which is located at the top, is connected to the oil collection channel 1.3, and the second oil chamber 1.22, which is located at the bottom, is connected to the reaction chamber 1.4.

[0098] The partition plate 1.12 has an oil passage 1.23 that connects the first oil chamber 1.21 and the second oil chamber 1.22; the upper end face of the partition plate 1.12 is inclined so that the liquid in the first oil chamber 1.21 can be guided to the oil passage 1.23, and the oil passage 1.23 is provided with an oil inlet control valve 1.24 to control its opening / closing.

[0099] Meanwhile, a drain pipe 1.13 is connected to the side wall of the first oil chamber 1.21 to drain the liquid inside the first oil chamber 1.21. The inlet port of the drain pipe 1.13 is connected to the first oil chamber 1.21 and is located near the bottom of the first oil chamber 1.21; the outlet port of the drain pipe 1.13 is connected to a sewer pipe. A level gauge 1.19 is installed in the second oil chamber 1.22 to monitor the liquid level inside the second oil chamber 1.22. The oil inlet control valve 1.24 is configured to be electrically connected to the control module and to close / open when the integrated stove turns on / off the oil drain mode.

[0100] Specifically, the control module supplies power to the oil inlet control valve 1.24 and controls its opening and closing. When the integrated stove is in oil drain mode, the control module closes the oil passage 1.23, allowing the cleaning liquid to be discharged from the drain pipe 1.13. When the integrated stove is in oil drain mode, the control module opens the oil passage 1.23. Waste oil remaining in the smoke collection chamber 1.1 during normal operation flows from the oil collection passage 1.3 into the first oil chamber 1.21 and then from the oil passage 1.23 into the second oil chamber 1.22 for storage. This continues until the level gauge 1.19 in the second oil chamber 1.22 detects that the waste oil level is greater than or equal to a set height. In this case, the control module controls the integrated stove to open the oil drain mode as described above, and closes the oil drain mode after a set time.

[0101] When flushing the fan 1.182 as described above, the fan casing 1.181 or the exhaust pipe 1.183 may also be provided with channels for liquid to flow into the smoke collection chamber 1.1, so as to better discharge the waste liquid generated after cleaning.

[0102] Furthermore, based on the above, in order to better improve the cleaning effect, as shown in the attached... Figure 4 As shown, the lower-level machine 1 is also equipped with a water tank 1.14, which stores water. The water tank 1.14 is connected to the drain pipe 1.6 through a water outlet pipe 1.15, and a second water pump 1.16 is installed in the water outlet pipe 1.15 to drive the water in the water tank 1.14 to flow into the drain pipe 1.6.

[0103] The second water pump 1.16 is configured to be electrically connected to the control module and to turn on / off when the integrated stove's oil drain mode is turned on / off. Specifically, the control module supplies power to the second water pump 1.16 and controls its on / off operation. When the integrated stove's oil drain mode is on, the control module controls the second water pump 1.16 to turn on, delivering water from the water tank 1.14 to the drain pipe 1.6. This water mixes with a solution containing higher fatty acid salts to spray and clean the components in the smoke collection chamber 1.1, increasing the spray pressure and thus improving the spraying effect. When the integrated stove's oil drain mode is off, the control module controls the second water pump 1.16 to turn off, ending the cleaning process.

[0104] Alternatively, the second water pump 1.16 is configured to be electrically connected to the control module, activating synchronously when the integrated stove's oil drain mode is activated, and deactivating delayed when the integrated stove's oil drain mode is deactivated. That is, the control module supplies power to the second water pump 1.16 and controls its activation / deactivation. When the integrated stove's oil drain mode is activated, the control module activates the second water pump 1.16, delivering water from the water tank 1.14 to the drain pipe 1.6. This water mixes with a solution containing higher fatty acid salts to spray and clean the components in the smoke collection chamber 1.1, increasing the spray pressure and thus improving the spraying effect. However, when the integrated stove's oil drain mode is deactivated, the control module controls the second water pump 1.16 to remain activated for a period of time before deactivating (this activation time is set according to actual needs) to perform a secondary cleaning with clean water.

[0105] Furthermore, as shown in the appendix Figure 4 As shown, the portion of the outlet pipe 1.15 near the drain pipe 1.6 may also be equipped with a one-way valve 1.17 that only allows liquid to flow from the outlet pipe 1.15 to the drain pipe 1.6. This is to minimize the risk of contamination of the water in the tank 1.14 by solutions containing higher fatty acid salts flowing into it.
